从BMP文件中装入位图并显示 the bmp file has four sections. the first is bitmapfileheader. this contains the bitmap file signature, the size of the bitmap and the offset to the array of bits that define the bitmap image. the next section is the bitmapinfoheader

图像中值滤波，利用中值滤波和低通滤波进行比较，分析PSNR，得出性能差别-image filtering, using median filter and a low-pass filter, PSNR analysis, the performance differences come

HSF processes the distorted image ˜ x by M filters chosen to improve the image quality for regions with different characteristics. At each pixel, a feature vector yn is computed using local image data. The feature vector is then used to determi

Image Filters for Noise Reduction in Images

in the existing technique gaussian denoising is performed to remove the noise in image. in the proposed technique rician denoising is performed to remove the noisy pixel
